Seed Planting Depth Guide.
Seeds are a general rule are planted to a depth of one and and half times the height of the seed.If the seed is planted too deep it will in some cases grow but it will suffer as it will have to expend to much of its stored energy in the seed.Once the seed is sown its worth making sure the soil or compost it well firmed in around the seed so that the seed can take up the available water or soil moisture to add germination.
